The article focuses on the challenges of assessing "reasonable safety" in existing structures and explores the impact of paradigm shifts in construction. Topics include the uncertainty surrounding safety evaluations, the influence of changing construction norms, and the importance of adapting to evolving industry practices to ensure accurate assessments of structural conditions.

The article informs about the challenges of visually surveying existing structures for safety assessment, emphasizing the limitations of visual surveys in identifying potential hazards and vulnerabilities. Topics include the significance of cracks and visual defects, the need for discernment in interpreting them, and the consideration of unexpected structural behavior in determining safety during the assessment of aging structures.

The article focuses on the evaluation of the safety of existing reinforced concrete structures, emphasizing the importance of understanding limitations and complexities in the assessment process. Topics discussed include the challenges associated with discoverable documentation, the evolution of building codes and their impact on safety assessments, and the vulnerabilities of common structural systems such as flat plate concrete slabs, post-tensioned concrete, and prestressed precast concrete.

The article discusses the increasing focus on safety assessments for existing structures by various authorities in different regions of the U.S. Topics include the challenges of determining the safety of these structures, limitations of condition surveys, and the need for regular surveys and assessments to document changes in conditions over time.

The article discusses the issue of corrosion of reinforcing steel in concrete, not only in exterior structures but also in interior environments that can be severely corrosive. It emphasizes the need for designers to consider the possibility of corrosive conditions in interior components and provides general guidelines for mitigation methods, such as limiting admixed chlorides and using supplementary cementitious materials (SCMs) to achieve durability.

The article provides an answer to a question concerning the shoring in structural repair projects.

The article presents the discussion on local initiatives by ACI in the Carolinas for advocating the incorporation of the ACI 562 Repair Code. Topics include implying a familiarity and understanding of the concepts as well as the potential impacts to the industry; and used for industrial or manufacturing processes impacting the durability and service life of existing structures.

The article informs that cathodic protection and concrete repairs at sound of the Sea II Condominiums. Topics include location of Sound of the Sea II makes it highly susceptible to chloride penetration from ocean-borne salts and associated corrosion-related distress of embedded steel; and coatings did not effectively arrest corrosion, as was evidenced by the formation of subsequent delaminations.

The article focuses on performance-based specifications that meet explicit durability goals can be successfully used on different types of construction projects. It mentions performance-based specifications for concrete mixture proportions to ensure durability and sustainability while minimizing cost and performance-related mixture and construction special provisions were incorporated into contract documents. It also mentions contractor chose to use a ternary cementitious and pavement mixture.
